INTRODUCTION

• The storage-area network (SAN) is a set of protocols and technologies that permit storage devices to have direct connections with servers over some distance. In addition, a SAN permits the storage devices to be shared among a number of servers based on select criteria. Finally, using VSAN technologies (virtual SAN), a group of discrete SANs can be connected together using a "virtual" SAN fabric.

WHY SAN?

• The following are some of the business drivers for SAN deployments:

• • Escalating storage requirements • • Rising storage management costs • • Business continuity • • Requirement to share information • • Increasing levels of underutilized disk storage resources resulting

in increased backup storage and backup handling costs• One disadvantage to SANs is that there is limited vendor

interoperability.

ADVANTANGES AND DISADVANTAGESAdvantages Disadvantages

The SAN's performance is directly linked to that of the type of network being used. In the case of a fibre channel network, the bandwidth is approximately 100 megabytes/second (1,000 megabits/second) and can be extended by increasing the number of access connections.

It is much more costly to acquire a SAN than a NAS because it is a complete architecture that uses technology that is still very expensive

A SAN's capacity can be extended almost limitlessly and can reach hundreds and even thousands of terabytes

Using a Storage Area Network is that it would be very difficult to keep up your data if it breaks down.

it is possible to share data between several network computers without sacrificing performance because SAN traffic is completely separate from user traffic

with regards to stability, functionality and speed, it's second to none.

SAN COMPONENTS

There are three main components to a SAN • Host Bus Adapters (HBA)• Data Storage Devices• Storage Subsystems

Page 7: Storage area network

HOST BUS ADAPTER

• An HBA is an I/O adapter that provides connectivity between a host server and a storage device. The HBA is used to connect a device to a SAN using a Fibre Channel interface. Intelligent HBAs perform many of the lower-level I/O functions to minimize the CPU impact on the host server. HBA connection methods can be either copper or fiber, similar to a typical LAN adapter.

DATA STORAGE DEVICES• Disk drives themselves cannot sit directly on the network. The

technologies listed represent the controller intelligence that enables the drives to be used. The means needed for physical connectivity may vary. There are several methods of connecting storage devices to their host CPUs:

• • Parallel SCSI copper interconnects • • Optical direct connect • • Fibre Channel switch

STORAGE SUBSYSTEMS• Storage Subsystems connect storage devices to the network. Storage

organization can be supported through various subsystems from simplistic to complex with large volumes of storage and many services available. Types of storage subsystems are:

➔Just a bunch of disks (JBOD)➔Storage arrays➔RAID

Page 10: Storage area network

RAID OVERVIEW• RAID is a method used to inexpensively put together a set

of physical hard drives into a logical array of storage devices. RAID provides fault tolerance compared to standalone disk drives. RAID does this by mirroring data or implementing parity check operations. RAID can be performed using hardware or host-based software. Several types of RAID can be used, including one or more of these:

• RAID 0 (striping)• RAID 1 (mirroring)• RAID 3 (error detection)• RAID 5 (error correction)
